Description
The SunPKCS11 symmetric cipher implementation contain an optimized code path for the engineUpdate(ByteBuffer, ByteBuffer) and engineDoFinal() methods if both the input and the output ByteBuffer are direct buffers. We should consider doing a partial optimization if only one of the two buffers is a direct buffer.
Comments
EVALUATION Updated the code so that SunPKCS11 provider can handle ByteBuffer input/output for both direct and non-direct type of byte buffers.
